Description

用于空调器的控制方法Control method for air conditioner 技术领域Technical field
本发明属于空调器技术领域,具体提供一种用于空调器的控制方法。The invention belongs to the technical field of air conditioners, and specifically provides a control method for an air conditioner.
背景技术Background technique
空调器是能够为室内制冷/制热的设备,随着时间的推移,空调器的室内机和室外机上的积灰会逐渐增多,积灰累积到一定程度后会滋生大量的细菌,尤其在室内空气流经室内机时,会携带大量的灰尘和细菌,因此需要对空调器及时进行清洁。The air conditioner is a device capable of cooling / heating the room. As time goes by, the ash accumulation on the indoor and outdoor units of the air conditioner will gradually increase. After the ash accumulation has accumulated to a certain extent, a large number of bacteria will grow, especially indoors. When the air flows through the indoor unit, it will carry a lot of dust and bacteria, so the air conditioner needs to be cleaned in time.
目前,空调器的清洁一般需要通过人工进行清洁或者通过按键启动自清洁装置进行清洁,但是由于用户不能很准确地判断空调器何时需要进行清洁,导致空调器不能被及时地清洁,从而影响用户的使用体验。现在的一些空调器也有采用自清洁的方式,例如公开号为CN107525209A的专利中公开了一种空调器自清洁控制方法,具体而言,该控制方法包括检测空调器当前的运行模式,若空调器当前的运行模式为非制冷模式,将空调器调整为制冷模式;检测空调器的室内机风机的电机的转速及电机在转速下的第一电流值;将电机在转速下的第一电流值与在转速下的第一预设电流值进行比较,若第一电流值小于或等于第一预设电流值,则开启空调器的自清洁模式,执行室内机换热器的自清洁处理。也就是说,上述的专利中采用的是通过室内机的风机电流来判断是否执行室内机的自清洁,然而,室内机的导板位置会影响室内机的风机电流,即导板的开口角度越小,室内机的出风量越小,风机的负荷越大,相应地,风机电流越小,而且,室内机的风速也会对风机电流产生影响,即风速越小,电流越小,因此,如果只通过室内机风机电流的单一条件判断无法确定室内机的电流降低到底是由于空调器的导板位置和/或风速大小产生还是由于空调器的结灰产生,如果空调器仅仅是由于室内机的导板开口角度变小和/或风速变小而使室内机的风机电流降低,那么可能会出现室内机在未结灰的情况下空调器仍然会对室内机进行自清洁,这就会造成能源上的浪费。At present, the cleaning of an air conditioner generally requires manual cleaning or a self-cleaning device activated by pressing a button. However, because the user cannot accurately determine when the air conditioner needs to be cleaned, the air conditioner cannot be cleaned in a timely manner, thereby affecting the user. Experience. Some current air conditioners also adopt a self-cleaning method. For example, a patent disclosed in CN107525209A discloses a self-cleaning control method for an air conditioner. Specifically, the control method includes detecting a current operating mode of the air conditioner. The current operating mode is a non-cooling mode, and the air conditioner is adjusted to a cooling mode; the speed of the motor of the indoor unit fan of the air conditioner and the first current value of the motor at the speed are detected; and the first current value of the motor at the speed and the The first preset current value at the rotation speed is compared. If the first current value is less than or equal to the first preset current value, the self-cleaning mode of the air conditioner is turned on, and the self-cleaning process of the indoor unit heat exchanger is performed. That is to say, the above-mentioned patent uses the fan current of the indoor unit to determine whether to perform self-cleaning of the indoor unit. However, the position of the guide plate of the indoor unit will affect the fan current of the indoor unit, that is, the smaller the opening angle of the guide plate, The smaller the amount of air output from the indoor unit, the larger the load on the fan, and accordingly, the smaller the fan current, and the wind speed of the indoor unit will also affect the fan current, that is, the smaller the wind speed, the smaller the current. The single condition judgment of the fan current of the indoor unit cannot determine whether the reduction of the indoor unit current is due to the position and / or wind speed of the air conditioner or due to the ashing of the air conditioner. If the air conditioner is only due to the opening angle of the air conditioner of the indoor unit The smaller and / or the lower the wind speed, which reduces the fan current of the indoor unit, it may happen that the indoor unit still cleans the indoor unit when the indoor unit is not dusty, which will cause a waste of energy.
因此,本领域需要一种用于空调器的控制方法来解决上述问题。Therefore, there is a need in the art for a control method for an air conditioner to solve the above problems.

在上述控制方法的优选技术方案中,“设定空调器的检测模式”的步骤具体包括:设定空调器的运行工况;设定室内机的导板位置和/或室内机的风速。In a preferred technical solution of the above control method, the step of "setting a detection mode of the air conditioner" specifically includes: setting an operating condition of the air conditioner; setting a position of a guide plate of the indoor unit and / or a wind speed of the indoor unit.
本领域技术人员能够理解的是,在本发明的优选技术方案中,首先给空 调器设定一个检测模式,在检测室内机的风机电流前,先将空调器调整到设定的检测模式,然后再获取空调器在设定模式下室内机的风机电流值,然后计算室内机的风机电流值相对于标准电流值的变化值,再将变化值与预设值进行比较,根据比较结果选择性地提示空调器需要被清洁,如果变化值大于预设值,则提示空调器需要被清洁,如果变化值不大于预设值,则不提示空调器需要被清洁。通过这样的控制方法,能够使用户准确地判断空调器是否需要被清洁,与现有技术中采用人工清洁空调器的方式相比,本发明中当空调器需要清洁时能够马上提示用户对空调器进行清洁,从而使空调器能够被及时地清洁,提升用户的使用体验。Those skilled in the art can understand that in the preferred technical solution of the present invention, a detection mode is first set for the air conditioner. Before detecting the fan current of the indoor unit, the air conditioner is first adjusted to the set detection mode, and then Then obtain the fan current value of the indoor unit of the air conditioner in the setting mode, and then calculate the change value of the fan current value of the indoor unit relative to the standard current value, and then compare the change value with a preset value, and selectively according to the comparison result The air conditioner needs to be cleaned. If the change value is greater than the preset value, the air conditioner needs to be cleaned. If the change value is not greater than the preset value, the air conditioner does not need to be cleaned. Through such a control method, the user can accurately determine whether the air conditioner needs to be cleaned. Compared with the method of manually cleaning the air conditioner in the prior art, when the air conditioner needs to be cleaned in the present invention, the user can immediately prompt the user about the air conditioner. Perform cleaning so that the air conditioner can be cleaned in a timely manner and improve the user experience.
此外,与现有技术中空调器采用自清洁的方式相比,本发明通过给空调器设定检测模式,即先将空调器调整到设定的检测模式(该设定的检测模式可以为在制定标准电流值时空调器的运行模式),再检测室内机的风机电流,通过这样的设置,可以避免空调器由于模式不一致而导致对风机电流产生影响,即在设定的检测模式下,可以使空调器当前的运行工况以及参数与制定检测模式时的运行工况以及参数保持一致,从而消除运行工况以及参数不一致对风机电流的影响,该设定的检测模式可以包括空调器的运行工况(例如制冷工况、制热工况或者除湿工况等)、室内机的导板位置以及室内机的风速大小三个要素,首先设定空调器的运行工况,例如,先使空调器在制热工况下(该运行工况可以为在制定标准电流值时空调器所处的运行工况)运行,然后将导板转动到设定位置(该设定位置可以为在制定标准电流值时导板所处的位置),再将风速调整到设定风速(该设定风速可以为在制定标准电流值时风速的大小),从而能够避免出现空调器由于运行工况不同以及室内机的导板开口角度变小和/或风速变小而误判为空调器结灰而频繁执行自清洁模式导致浪费能源的情况,从而可以更为精准地判断何时才需要对空调器进行清洁,即在最合适的时间来对空调器进行自清洁,提升用户体验。In addition, compared with the self-cleaning method of the air conditioner in the prior art, by setting a detection mode for the air conditioner, the present invention first adjusts the air conditioner to a set detection mode (the set detection mode may be The operating mode of the air conditioner when setting the standard current value), and then the fan current of the indoor unit is detected. With this setting, the influence of the air conditioner on the fan current due to inconsistent modes can be avoided, that is, in the set detection mode, it is possible to Make the current operating conditions and parameters of the air conditioner consistent with the operating conditions and parameters when setting the detection mode, thereby eliminating the impact of the operating conditions and parameter inconsistencies on the fan current. The set detection mode can include the operation of the air conditioner The operating conditions (such as cooling, heating, or dehumidifying conditions), the position of the guide plate of the indoor unit, and the wind speed of the indoor unit are the three elements. First, set the operating conditions of the air conditioner. For example, first make the air conditioner Operate under heating conditions (this operating condition can be the operating condition of the air conditioner when setting the standard current value), and then turn the guide plate Set position (the set position can be the position of the guide plate when setting the standard current value), and then adjust the wind speed to the set wind speed (the set wind speed can be the size of the wind speed when setting the standard current value), so that It can prevent the air conditioner from being misjudged as the air conditioner is ashing due to different operating conditions and the opening angle of the guide plate of the indoor unit is reduced and / or the wind speed is reduced. Frequently performing the self-cleaning mode causes waste of energy, which can be more accurate. To determine when it is necessary to clean the air conditioner, that is, to self-clean the air conditioner at the most appropriate time to improve the user experience.
进一步地,标准电流值为空调器处在完全清洁且空调器在设定的检测模式下室内机的风机电流值,在空调器处于完全清洁的状态时,此时选取标准电流值更能够反馈空调器在使用过程中的结灰程度,即空调器在使用的过程中始终是和完全清洁状态下的风机电流参数进行比对,在消除空调器运行模式对风机电流影响的基础上,可以更加准确地反馈空调器的结灰程度,在结灰严重时可以及时提示用户需要对空调器进行清洁,在未结灰并且结灰程度 在可以接受的范围内时可以暂时不提示用户对空调器进行清洁。Further, the standard current value is the fan current value of the indoor unit when the air conditioner is completely clean and the air conditioner is in a set detection mode. When the air conditioner is completely clean, selecting the standard current value at this time can better feedback the air conditioner. The degree of ash formation during the use of the air conditioner, that is, the air conditioner is always compared with the fan current parameters in a completely clean state during use. It can be more accurate on the basis of eliminating the effect of the air conditioner operation mode on the fan current. The ground feedback of the ashing degree of the air conditioner can prompt the user to clean the air conditioner when the ashing is serious. When the ashing is not ashing and the ashing degree is within an acceptable range, the user can be temporarily not prompted to clean the air conditioner. .
更进一步地,提示空调器需要被清洁的方式采取将室内机上的指示灯变为红色可以使用户更为直观地观察到空调器需要被清洁,从而使用户及时对空调器进行人工清洁或开启空调器自清洁模式,避免空调器由于清洁不及时而导致脏堵严重进而影响用户的正常体验。Furthermore, the method of prompting the air conditioner to be cleaned by taking the indicator light on the indoor unit to red can make the user more intuitively observe that the air conditioner needs to be cleaned, so that the user can manually clean the air conditioner or turn on the air conditioner in time. The self-cleaning mode of the air conditioner prevents serious blockage of the air conditioner due to untimely cleaning, thereby affecting the normal experience of the user.

具体实施方式detailed description
下面参照附图来描述本发明的优选实施例。本领域技术人员应当理解的是,这些实施例仅仅用于解释本发明的技术原理,并非旨在限制本发明的保护范围。Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.
基于背景技术指出的现有空调器10采用人工清洁无法使用户准确地判断何时需要对空调器10进行清洁,从而使空调器10不能被及时地清洁,以及空调器10采用自清洁方式容易使空调器10出现误判而频繁执行自清洁的问题。本发明提供了一种用于空调器10的控制方法,旨在使空调器10在需要进行清洁时能够提示用户对空调器10进行清洁,从而使空调器10能够被及时地清洁,进而提升用户体验。The existing air conditioner 10 using manual cleaning based on the background art cannot enable the user to accurately determine when the air conditioner 10 needs to be cleaned, so that the air conditioner 10 cannot be cleaned in a timely manner, and the air conditioner 10 is self-cleaning and easy to use. The air conditioner 10 has a problem of misjudgment and frequently performs self-cleaning. The invention provides a control method for an air conditioner 10, which aims to enable the air conditioner 10 to prompt a user to clean the air conditioner 10 when cleaning is needed, so that the air conditioner 10 can be cleaned in time, thereby improving users Experience.
具体地,参见图4,本发明的空调器10包括室内机20,如图1所示,本发明的控制方法包括:步骤S104,将空调器10调整到设定的检测模式;步骤S106,获取空调器10在设定的检测模式下室内机20的风机电流值;步骤S108,根据风机电流值,选择性地提示空调器10需要被清洁。需要说明的是,室内机20的风机电流大小能够直接反映出空调器10的结灰程度,因为在空调器10的运行模式固定的情况下风机40的负荷是确定的,如果当空调器10在相同运行模式下风机40的负荷增大,相应地,风机电流减小,此时说明风机40的风阻增加,也就是说室内机20上结灰,并且结灰越严重,风机电流就越小,因此,通过风机电流大小能够充分地判断空调器10的室内机20的结灰程度。Specifically, referring to FIG. 4, the air conditioner 10 of the present invention includes an indoor unit 20. As shown in FIG. 1, the control method of the present invention includes: Step S104, adjusting the air conditioner 10 to a set detection mode; Step S106, obtaining The fan current value of the indoor unit 20 in the set detection mode of the air conditioner 10; step S108, according to the fan current value, selectively prompting the air conditioner 10 to be cleaned. It should be noted that the magnitude of the fan current of the indoor unit 20 can directly reflect the degree of ash formation of the air conditioner 10 because the load of the fan 40 is determined when the operation mode of the air conditioner 10 is fixed. In the same operating mode, the load of the fan 40 increases, and accordingly, the fan current decreases. At this time, the wind resistance of the fan 40 increases, that is, the ash is formed on the indoor unit 20, and the more the ash is formed, the smaller the fan current is. Therefore, the degree of ash formation of the indoor unit 20 of the air conditioner 10 can be sufficiently determined based on the magnitude of the fan current.
优选地,如图2所示,“将空调器10调整到设定的检测模式”的步骤之前,控制方法还包括:步骤S102,设定空调器10的检测模式。“设定空调器10的检测模式”的步骤具体包括:设定空调器10的运行工况,设定室内机20的导板50的位置,设定室内机20的风速,在一个可选实施例中,风速可以为室内机10的风机40的转速;当然,作为替代性的,“设定空调器10的检测模式”的步骤具体包括:设定空调器10的运行工况,设定室内机20的导板50的位置,再或者,“设定空调器10的检测模式”的步骤还可以包括:设定空调器10的运行工况,设定室内机20的风速。其中,空调器10的运行工况可以设定为制冷工况,或者设置为制热工况,再或者设置为除湿工况;而导板50的位置可以设置为导板50开口角度为30度的位置,或者设置为导板50开口角度为45度的位置,再或者设置为导板50开口角度为60度的位置;而风速可以设置为低档风速,或者设置为中档风速,再或者设置为高档风速,本领域技术人员可以在实际应用中灵活地设置空调器10运行的具体工况,导板50的具体位置以及风速的具体大小。此外,在空调器10的每一种运行工况下都设定一种对应的检测模式,通过这样的设置,即设定多种检测模式,使空调器10在进入设定的检测模式时仅仅需要调整导板50的位置和/或风速的大小即可,不必再调整空调器10的运行工况。例如,假如仅设定一种检测模式且该设定的检测模式是空调器10在制热工况下设定的,然而,当前空调器10在制冷工况下运行,当需要检测风机电流时,就需要先把空调器10由制冷工况调整到制热工况,如果空调器10在制冷工况下也设定有一种对应的检测模式,则仅需要调整导板50的位置和/或风速的大小即可,不必再调整空调器10的运行工况,从而能够既节省时间又节约能源,进而提高用户使用体验。当然,在空调器10的每一种运行工况下不仅限于一种对应的检测模式,可以设定两种或者三种等。Preferably, as shown in FIG. 2, before the step of “adjusting the air conditioner 10 to a set detection mode”, the control method further includes: Step S102, setting a detection mode of the air conditioner 10. The steps of “setting the detection mode of the air conditioner 10” specifically include: setting the operating conditions of the air conditioner 10, setting the position of the guide plate 50 of the indoor unit 20, and setting the wind speed of the indoor unit 20. In an alternative embodiment, The wind speed may be the rotation speed of the fan 40 of the indoor unit 10. Of course, as an alternative, the step of “setting the detection mode of the air conditioner 10” specifically includes: setting the operating conditions of the air conditioner 10, and setting the indoor unit. The position of the guide plate 50 of 20, or the step of "setting the detection mode of the air conditioner 10" may further include: setting an operating condition of the air conditioner 10, and setting a wind speed of the indoor unit 20. The operating condition of the air conditioner 10 can be set to a cooling condition, a heating condition, or a dehumidification condition; and the position of the guide plate 50 can be set to a position where the opening angle of the guide plate 50 is 30 degrees. , Or set to the position where the opening angle of the guide plate 50 is 45 degrees, or set to the position where the opening angle of the guide plate 50 is 60 degrees; and the wind speed can be set to a low-speed wind speed, or a mid-range wind speed, or a high-end wind speed. Those skilled in the art can flexibly set the specific operating conditions of the air conditioner 10, the specific position of the guide plate 50, and the specific size of the wind speed in actual applications. In addition, a corresponding detection mode is set under each operating condition of the air conditioner 10, and through such a setting, multiple detection modes are set so that the air conditioner 10 only enters the set detection mode when It is only necessary to adjust the position of the guide plate 50 and / or the magnitude of the wind speed, and it is not necessary to adjust the operating conditions of the air conditioner 10 again. For example, if only one detection mode is set and the set detection mode is set in the heating condition of the air conditioner 10, however, the current air conditioner 10 is operating in the cooling condition, and when it is necessary to detect the fan current , It is necessary to first adjust the air conditioner 10 from the cooling mode to the heating mode. If the air conditioner 10 is also set with a corresponding detection mode under the cooling mode, only the position and / or wind speed of the guide plate 50 need to be adjusted. It is only necessary to adjust the operating conditions of the air conditioner 10, thereby saving time and energy and improving the user experience. Of course, under each operating condition of the air conditioner 10, it is not limited to one corresponding detection mode, and two or three types can be set.
优选地,“将空调器10调整到设定的检测模式”的步骤包括:每隔预设时间,空调器10自动调整到设定的检测模式,其中,预设时间可以是一小时,即空调器10每运行一小时后自动调整到设定的检测模式,当然,上述的预设时间不限于一小时,还可以是一天、一周或者为任意设定的一段时间,本领域技术人员可以在实际应用中灵活地设置预设时间的时长,只要空调器10每隔预设时间能够自动调整到设定的检测模式即可。当然,作为替代性的,“将空调器10调整到设定的检测模式”的步骤包括,空调器10根 据用户指令调整到设定的检测模式,即需要用户手动操作,将空调器10调整到设定的检测模式;再或者,“将空调器10调整到设定的检测模式”的步骤还包括,空调器10每隔预设时间和根据用户指令调整的设定的检测模式,本领域技术人员可以在实际应用中灵活地设置将空调器10调整到预设的检测模式的方式,例如,使空调机每隔预设时间主动调整到设定的检测模式,或者,通过用户的指令使空调器10调整到设定的检测模式,再或者,通过述两种方式均能够使空调器10调整到设定的检测模式,只要能够使空调器10进入设定的检测模式即可,这种对空调器10调整到设定的检测模式的方式的调整和改变并不偏离本发明的原理和范围,均应限定在本发明的保护范围之内。下面结合具体实施例详细地阐述本发明的技术方案。Preferably, the step of “adjusting the air conditioner 10 to a set detection mode” includes: every predetermined time, the air conditioner 10 is automatically adjusted to the set detection mode, wherein the preset time may be one hour, that is, the air conditioner The device 10 automatically adjusts to the set detection mode after each hour of operation. Of course, the above-mentioned preset time is not limited to one hour, but can also be one day, one week, or an arbitrary set period of time. The duration of the preset time can be flexibly set in the application, as long as the air conditioner 10 can automatically adjust to the set detection mode every preset time. Of course, as an alternative, the step of “adjusting the air conditioner 10 to the set detection mode” includes that the air conditioner 10 is adjusted to the set detection mode according to a user instruction, that is, a manual operation of the user is required to adjust the air conditioner 10 to A set detection mode; or, the step of “adjusting the air conditioner 10 to the set detection mode” further includes: the air conditioner 10 is set at a preset time and a set detection mode adjusted according to a user instruction. Personnel can flexibly set the way to adjust the air conditioner 10 to a preset detection mode in practical applications, for example, to make the air conditioner actively adjust to the set detection mode every preset time, or to make the air conditioner through a user's instruction The air conditioner 10 is adjusted to the set detection mode, or alternatively, the air conditioner 10 can be adjusted to the set detection mode by the two methods described above, as long as the air conditioner 10 can enter the set detection mode. The adjustment and change of the manner in which the air conditioner 10 is adjusted to the set detection mode does not deviate from the principle and scope of the present invention, and should be limited to the protection scope of the present invention. The technical solution of the present invention is described in detail below with reference to specific embodiments.
优选地,如图3所示,“根据风机电流值,选择性地提示空调器10需要被清洁”的步骤具体包括:步骤S208,计算风机电流值相对于标准电流值的变化值;步骤S210,判断变化值是否大于预设值。也即是,将变化值与预设值比较;根据比较结果,选择性地提示空调器10需要被清洁。进一步地,“根据比较结果,选择性地提示空调器10需要被清洁”的步骤包括:如果变化值大于预设值,则提示空调器10需要被清洁(步骤S212);如果变化值不大于预设值,则不提示空调器10需要被清洁(步骤S214)。具体地,上述的变化值等于标准电流值Ib与风机电流值If的差值△I。即,如果标准电流值Ib与风机电流值If的差值△I大于预设值,则提示空调器10需要被清洁,如果标准电流值Ib与风机电流值If的差值△I不大于预设值,则不提示空调器10需要被清洁。在一种可能的实施例中,预设值设置为0.1A,即如果△I>0.1A,则说明此时室内机20的脏堵比较严重,需要提示用户对空调器10进行清洁,如果△I≤0.1A,则说明此时室内机20无脏堵或者室内机20的脏堵仍然在可以接受的范围内,此时可以暂时不提示用户对空调器10进行清洁。当然,预设值不限于上述示例的0.1A,本领域技术人员可以在实际应用中灵活地设置预设值的具体数值,只要通过预设值确定的分界点能够判断空调器10是否需要被清洁即可。Preferably, as shown in FIG. 3, the step of “optionally prompting the air conditioner 10 to be cleaned according to the fan current value” specifically includes: step S208, calculating a change value of the fan current value relative to the standard current value; step S210, Determine whether the change value is greater than a preset value. That is, the change value is compared with a preset value; according to the comparison result, the air conditioner 10 is selectively prompted to be cleaned. Further, the step of “selectively prompting the air conditioner 10 to be cleaned according to the comparison result” includes: if the change value is greater than a preset value, prompting the air conditioner 10 to be cleaned (step S212); if the change value is not greater than the preset value If the value is set, the air conditioner 10 is not prompted to be cleaned (step S214). Specifically, the above-mentioned change value is equal to the difference ΔI between the standard current value Ib and the fan current value If. That is, if the difference ΔI between the standard current value Ib and the fan current value If is greater than a preset value, it is prompted that the air conditioner 10 needs to be cleaned. If the difference △ I between the standard current value Ib and the fan current value If is not greater than the preset value Value, it does not indicate that the air conditioner 10 needs to be cleaned. In a possible embodiment, the preset value is set to 0.1A, that is, if △ I> 0.1A, it means that the dirty blockage of the indoor unit 20 is serious at this time, and the user needs to be prompted to clean the air conditioner 10, if △ If I≤0.1A, it means that there is no dirty blockage of the indoor unit 20 or the dirty blockage of the indoor unit 20 is still within an acceptable range. At this time, the user may not be prompted to clean the air conditioner 10 temporarily. Of course, the preset value is not limited to the above-mentioned example 0.1A. Those skilled in the art can flexibly set the specific value of the preset value in practical applications, as long as the cut-off point determined by the preset value can determine whether the air conditioner 10 needs to be cleaned. Just fine.
此外,还需要说明的是,上述的标准电流值可以在空调器10出厂前进行测定,即空调器10处于完全清洁的状态下,测定空调器10在设定的检测模式下室内机20的标准电流值。此外,标准电流值还可以在空调器10出厂后进行测定,即空调器10在使用过程中,将预设时间内获取的空调器10在 设定的检测模式下室内机20的多个风机电流值中出现频次最高的电流值作为标准电流值,通过对多个风机电流值出现频次的计算和排序,来选取出现频次最高的风机电流值作为标准电流值,其中,风机电流值的采样数据可以为1000个、2000个或者其他数量,本领域技术人员可以在实际应用中灵活地设置风机电流值的采样数量。而预设时间可以是一天、一周、一个月或者其他设定的时间数值,只要从预设时间内获取的多个风机电流值能够选定出标准电流值即可,这种对预设时间具体数值的调整和改变并不偏离本发明的原理和范围,均应限定在本发明的保护范围之内。In addition, it should be noted that the above-mentioned standard current value can be measured before the air conditioner 10 leaves the factory, that is, when the air conditioner 10 is in a completely clean state, the standard of the indoor unit 20 is measured under the set detection mode of the air conditioner 10 Current value. In addition, the standard current value can also be measured after the air conditioner 10 leaves the factory, that is, during the use of the air conditioner 10, the air current of the air conditioner 10 obtained in a preset time in a set detection mode of multiple fan currents of the indoor unit 20 The current value with the highest frequency among the values is used as the standard current value. By calculating and sorting the frequency of multiple fan current values, the fan current value with the highest frequency is selected as the standard current value. The sampling data of the fan current value can be For 1000, 2000 or other numbers, those skilled in the art can flexibly set the number of samples of the fan current value in practical applications. The preset time can be one day, one week, one month, or other set time value, as long as a plurality of fan current values obtained from the preset time can select a standard current value, which is specific to the preset time The adjustment and change of the values do not deviate from the principle and scope of the present invention, and should be limited to the protection scope of the present invention.
进一步优选地,“提示空调器10需要被清洁”的步骤包括:将室内机20上的指示灯60变为预警颜色,其中,可以通过使室内机20上的指示灯60变为红色或者黄色来提示用户空调器10需要被清洁,本领域技术人员可以在实际应用中灵活地设定指示灯60的具体颜色,只要通过该颜色的选定能够提示用户需要对空调器10进行清洁即可,当然,在实际应用中,还可以通过室内机20上的声音装置(例如蜂鸣器、语音播报器等)发出声音来提示用户空调器10需要被清洁,再或者通过指示灯60和声音装置的组合共同提示用户空调器10需要被清洁,本领域技术人员可以在实际应用中灵活地设置用户对空调器10进行清洁的具体提示方式,这种对提示方式的调整和改变并不偏离本发明的原理和范围,均应限定在本发明的保护范围之内。Further preferably, the step of “indicating that the air conditioner 10 needs to be cleaned” includes: changing the indicator light 60 on the indoor unit 20 to a warning color, wherein the indicator light 60 on the indoor unit 20 can be changed to red or yellow to Prompts the user that the air conditioner 10 needs to be cleaned. Those skilled in the art can flexibly set the specific color of the indicator 60 in practical applications, as long as the selection of the color can prompt the user to clean the air conditioner 10, of course. In actual applications, a sound device (such as a buzzer, a voice announcer, etc.) on the indoor unit 20 can also be used to prompt the user that the air conditioner 10 needs to be cleaned, or a combination of the indicator light 60 and the sound device The user is reminded that the air conditioner 10 needs to be cleaned. Those skilled in the art can flexibly set the specific prompting method for the user to clean the air conditioner 10 in practical applications. Such adjustments and changes to the prompting method do not deviate from the principle of the present invention. And the scope should be limited within the protection scope of the present invention.
需要说明的是,当用户被提示空调器10需要清洁时可以对空调器10的室内机20单独进行清洁,也可以对空调器10的室内机20和室外机同时进行清洁,因为室内机20出现脏堵时也能够在一定程度上间接反馈出室外机也到了出现脏堵的时限。此外,在本发明中,对空调器10具体的清洁方式可以是人工进行清洁,也可以是启动空调器10的自清洁装置进行清洁。本发明的空调器10还包括控制器,该控制器配置成能够执行上述的控制方法。It should be noted that when the user is prompted that the air conditioner 10 needs to be cleaned, the indoor unit 20 of the air conditioner 10 can be cleaned separately, and the indoor unit 20 and the outdoor unit of the air conditioner 10 can be cleaned simultaneously because the indoor unit 20 appears It can also indirectly feedback the outdoor unit to a certain extent when the dirty blockage has reached the time when the dirty blockage occurs. In addition, in the present invention, the specific cleaning method for the air conditioner 10 may be manual cleaning, or it may be a self-cleaning device that starts the air conditioner 10 for cleaning. The air conditioner 10 of the present invention further includes a controller configured to be able to perform the above-mentioned control method.
至此,已经结合附图所示的优选实施例描述了本发明的技术方案,但是,本领域技术人员容易理解的是,本发明的保护范围显然不局限于这些具体实施例。在不偏离本发明的原理的前提下,本领域技术人员可以对相关技术特征作出等同的更改或替换,这些更改或替换之后的技术方案都将落入本发明的保护范围之内。So far, the technical solution of the present invention has been described with reference to the preferred embodiments shown in the accompanying drawings. However, those skilled in the art can easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or replacements to related technical features, and the technical solutions after these changes or replacements will fall within the protection scope of the present invention.
